If your vehicle is an older model with a non-electronic Fuel And Air Metering, you can check the distributor
cap to see whether the spark is getting from there to the coil and on to the spark plugs.

Don't forget ! If your P217b engine code not resolved on
and there are trouble codes in your computer, your vehicle will not pass an OBD 2
emissions test. The light must be off and there must be no codes in memory to pass an OBD 2
emissions test. In addition, all of the OBD II self-monitors that check for faults must have run and
completed without finding any further problems to pass the test.
